Neoterramycin, also known as neomycin B, is an aminoglycoside antibiotic derived from the bacterium Streptomyces fradiae. It is primarily used to treat bacterial infections, particularly those caused by gram-negative bacteria, and is effective against a wide range of pathogens. Neoterramycin works by binding to the 30S ribosomal subunit in bacterial cells, inhibiting protein synthesis and ultimately leading to cell death. It is commonly used topically for skin infections and orally for gastrointestinal infections, but it is not recommended for systemic use due to potential nephrotoxicity and ototoxicity. The antibiotic is also used as a growth promoter in animal husbandry, although its use is restricted in some countries due to concerns about antibiotic resistance.
The CAS Registry Mumber 8057-00-9 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 8,0,5 and 7 respectively; the second part has 2 digits, 0 and 0 respectively. Calculate Digit Verification of CAS Registry Number 8057-00: (6*8)+(5*0)+(4*5)+(3*7)+(2*0)+(1*0)=89 89 % 10 = 9 So 8057-00-9 is a valid CAS Registry Number.
